Demystification of AI Carbon Accounting:
The Core Formulas Broken Down ⚡📊Measuring the true climate footprint of Artificial Intelligence requires looking beyond crude IT spend proxies and into precise telemetry.
To calculate total $CO_2e$ emissions across training and inference, three core variables drive the core calculation:
1️⃣ Energy ($\text{IT Load}$): Measured via GPU/TPU hours and power draw.
2️⃣ Grid Carbon Intensity ($\text{Grid CI}$): Varies dramatically by region and time of day based on the energy mix (coal vs. renewables).
3️⃣ Power Usage Effectiveness ($\text{PUE}$): The data center efficiency overhead multiplier (cooling, power conversion, facility overhead).Pair these with amortized hardware embodied carbon and functional unit metrics (tokens, queries, or generated assets) to build a robust Scope 2 and Scope 3 disclosure foundation for your ESG reporting. 🌿
